Bending tool

Abstract

A bending tool for bending elongate members. The bending tool includes a support (12a/28) such as a support frame (28) for supporting the elongate member (40) and also includes a bending member (15a/32/34) such as a pusher member (15a) whereby the bending member (15a/32/34 may abut the elongate member (40). When either the bending member (15a/32/34) or support member (12a/28) is moved relative to the other this may cause bending of the elongate member (40). The bending tool also includes actuating members (10a/22a) for causing said relative movement between the support member (12a/28) and the bending member (15a/32/34).

I claim: 
     
       1. A bending tool for bending elongate members including; an elongated support frame;   an abutment block attached to said support frame;   a pusher member movably mounted to the support frame, said pusher member having a working end surface and a mounting end having a mating bore;   a pair of opposed recesses, for positioning a workpiece transversely with respect to the support frame, located on opposite sides of the support frame;   a pair of handles;   linkage means interconnecting each handle to the support frame;   a longitudinal shaft screw threadedly mounted in said mating bore and extending parallel to the length of the support frame whereby said pusher member is adjustably movable, by said shaft screw, relative to the abutment block;   pivot means interconnecting said shaft screw to each of said handles; and   locking means for selectively locking the shaft screw against movement in a selected position in the mating bore of the pusher member;   the construction and arrangement being such that upon movement of said handles toward and away from each other said pusher block moves longitudinally with respect to said support frame relative to the abutment block and when an elongate member is located in said recesses and transversely of the support frame and interposed between the pusher member and the abutment block said longitudinal movement of the pusher member bends said elongate member and upon release of said locking means said pusher member may be adjustably moved on said shaft relative to the abutment block.   
     
     
       2. A bending tool as claimed in claim 1, wherein the support frame includes a pair of opposed side members and said pusher block is mounted in opposed grooves wherein each groove is located in a respective side member. 
     
     
       3. A bending tool as claimed in claim 1, wherein the pusher member has a leading end proximal to the abutment block of substantially conical or tapered shape which locates in a recess in the abutment block upon actuating movement of said handles. 
     
     
       4. A bending tool as claimed in claim 1, wherein said abutment block is integral with said support frame. 
     
     
       5. A bending tool as claimed in claim 1, wherein said linkage means includes a pair of opposed toggle connectors connecting a respective handle to said support means.
